RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Vinzenz Feenstra [evilissimo] 2015-06-29 13:18:26 UTC 
+++ This bug was initially created as a clone of Bug #1236581 +++

Description of problem:
Currently the connected, initialized and disconnected spice events reported by libvirt contain a 'service' field with an empty value.


Actual results:

service field is empty

Expected results:

service field contains the port of the remote and local service

Additional info:


The reason for this is, that the code in libvirt erroneously tries to extract the 'service' field from the event sent through qmp monitor.
The field however on spice events is called 'port'

    qemu: event: Clean up VNC monitor handling
    
    Get rid of spice specific stuff from the handler func and save a few
    lines by reflowing the conditions.

commit 8df888a532db0994519bbe0d9900f622ef3e3922
Author: Peter Krempa <pkrempa>

    qemu: event: Properly handle spice events
    
    Spice events have mostly similar information present in the event JSON
    but they differ in the name of the element containing the port.
    
    The JSON event also provides connection ID which might be useful in the
    future.
    
    This patch splits up the event parser code into two functions and the
    SPICE reimplements the event parsing with correct names and drops the
    VNC only stuff.

Comment 3 Fangge Jin 2015-07-16 09:46:22 UTC 
Reproduce this bug on build libvirt-1.2.16-1.el7.x86_64:

1.Prepare a running guest with spice and vnc graphic:
# virsh dumpxml r71 
    <graphics type='vnc' port='5902' autoport='yes' listen='0.0.0.0'>
      <listen type='address' address='0.0.0.0'/>
    </graphics>
    <graphics type='spice' port='5903' autoport='yes' listen='0.0.0.0'>
      <listen type='address' address='0.0.0.0'/>
    </graphics>

2.# virsh event --loop --event graphics

3. Connect to r71 with spice and then close:
# remote-viewer spice://10.66.6.6:5903

4.Check the output of "virsh event":
event 'graphics' for domain r71: connect local[IPv4 10.66.6.6 ] remote[IPv4 10.66.6.6 ] 
event 'graphics' for domain r71: initialize local[IPv4 10.66.6.6 ] remote[IPv4 10.66.6.6 ] none
...............
event 'graphics' for domain r71: disconnect local[IPv4 10.66.6.6 ] remote[IPv4 10.66.6.6 ] 
...............

5.Connect to r71 with vnc and then close:
#remote-viewer vnc://10.66.6.6:5902

6.Check the output of "virsh event":
event 'graphics' for domain r71: connect local[IPv4 0.0.0.0 5902] remote[IPv4 10.66.6.6 33167] none
event 'graphics' for domain r71: initialize local[IPv4 0.0.0.0 5902] remote[IPv4 10.66.6.6 33167] none
event 'graphics' for domain r71: disconnect local[IPv4 0.0.0.0 5902] remote[IPv4 10.66.6.6 33167] none

As we can see, spice events miss the port.


Verify this bug on build libvirt-1.2.17-2.el7.x86_64:
1. Connect to r71 with spice and then close:
# remote-viewer spice://10.66.6.6:5903

2.Check the output of "virsh event":
event 'graphics' for domain r71: connect local[IPv4 10.66.6.6 5903] remote[IPv4 10.66.6.6 48910] 
event 'graphics' for domain r71: initialize local[IPv4 10.66.6.6 5903] remote[IPv4 10.66.6.6 48910] none
................
event 'graphics' for domain r71: disconnect local[IPv4 10.66.6.6 5903] remote[IPv4 10.66.6.6 48910] 
...............


3.Connect to r71 with vnc and then close:
#remote-viewer vnc://10.66.6.6:5902

4.Check the output of "virsh event":
event 'graphics' for domain r71: connect local[IPv4 0.0.0.0 5902] remote[IPv4 10.66.6.6 39167] none
event 'graphics' for domain r71: initialize local[IPv4 0.0.0.0 5902] remote[IPv4 10.66.6.6 39167] none
event 'graphics' for domain r71: disconnect local[IPv4 0.0.0.0 5902] remote[IPv4 10.66.6.6 39167] none

As we can see, both spice and vnc events have port.


Are the steps above enough to verify this bug?
